Tsk_recover failure with ewf file

Edward Diener
The failure I am about to describe occurs on both TSK 4.2.0 and the
recently released TSK 4.3.0 on Windows 8.1 using the binaries provided.

I use a program called FTK Imager Lite 3.1.1.8 from AccessData to create
ewf images. If I create ewf images from a single logical drive, which
naturally has a single file system, TSK and tsk_recover work fine.
Instead my problem with TSK is when creating ewf images from a physical
drive, which has a number of different file systems. In my example I
create ewf images from a physical drive which has separate FAT32, NTFS,
EXT3, and EXT4 with files in each logical partition. The FTK Imager Lite
program creates the ewf image for me in the directory of my choice from
the physical drive without any problems. I then run tsk_recover with the
-v verbose option, passing the full path to the ewf image and the
directory where I want the files to be put. The results of running
tsk_recover are:

--------------------------------------------------------------------------------------------------------------------------------

Yet if I ask FTK Imager to show me the file in the ewf image, using its
Add Evidence Item...
functionality it does indeed show me the files in the image without any
errors.

Is TSK supposed to work with physical drives containin different file
systems ? If so can anyone
suggest how I can get TSK to work properly ?
